Jim personally if I were you on a lower cost unit like this I might reconsider. Stihl, Husqvarna, Dolmar, nor Echo make those seals, they are sourced from an outside vendor. When you go to a bearing supply house (around here the main ones are Motion Industries (Used to be Dixie Bearing) Global Bearing, and INF Bearing) all you are doing is buying the part directly from a wholesale distributor and cutting out the OEM 200%+ markup. Now as an authorized dealer I cannot do that, I have to use OEM parts, but an independent repair shop can do it as long as the customer is made aware up front and given the three options, OEM, aftermarket, or decline the repair.
